Dalian about the problem of heating in winter is not hot.

According to your description, it is estimated that it belongs to an old building before the 1990s. In fact, the heating problem has nothing to do with the ownership, because the maintenance of heating is the responsibility of the heating unit and is not within the scope of the housing repair fund. Generally, in an old building like this, there are many reasons why the heating is not hot (the room temperature is less than), such as the age of the building, the blockage of heating pipes, the small number of radiators originally designed, and the heating quality of heating units. If the "not radiator" mentioned in the question means that the radiator will burn your hands when there is heating, which means that you only burn two ends a day during the heating period, then your best way is for the whole building to unite and write a letter to the municipal government, and the residents of the whole building will sign it once a week. As long as it is transferred from the city to the heating office, the heating office will definitely urge the heating unit to solve the problem, especially the problem of insufficient heating time like this. It's no use just looking for a boiler room or a heating unit over and over again. The boiler room is full of workers, so how to burn it depends on the leader.
